Hello,

I have question, I've read that you need to register new rims in a car and that your need some paper work to do that.
So, I bought a used car with original wheels on it, I also got steel wheels (original are alloys) with winter tires on them.
Now, I didn't get any paper / certificate with this, will I need to get this?
When is some kind of paper /certificate needed and when not (and how can I check this) ?

Regards

I think you may have been misinformed. Where did you read it?

This was mentioned for example here: Buying Rims and Tyres abroad

Also CH sites sellings rims / tires are issuing CH Zulassungszertifikat

No paperwork needed if original equipment/specified for the car. If the wheels were purchased in CH there will no issue.

Not necessarily, my car had all original parts, and the STVA( Strassenverkehrsamt ) requested that I provide an
"Eignungserklärung für die Felgen" translated Suitability Certificate
for the Rims.

I had to go to the Ford Dealer to get this certificate.

Are they of the approved size/diameter?
No "pimp my ride" kind of thing?

Standard that I got at the Ford dealer.

Ok but this was just for rims and not tires, correct?

From what I've been able to ascertain via the Basel/Zurich STVA and other's experiences, any OEM wheels that are listed on the COC as being suitable for the vehicle do not need an additional certificate (the COC will give the sizes, not the wheel model). So maybe they were not listed on the COC?

I think the same applies for tyres as well - they should be listed on the COC. Perhaps because 'non-standard' sizes and rims affect speedo readings.

Ref non-OEM wheels - I've just imported a car from Germany with 3rd party alloys. I asked the Strassenverkehrsamt (SH) what was needed and they are happy to accept either a Swiss certificate (from the Swiss wheel importer - if there is one and I pay a fee) or the German equivalent (ABE) which should be provided by the dealer/garage supplying the wheels.

Note that for wheels sourced from Germany, a 'TUV' certificate is not sufficient.

If the rims are non-standard & if the previous owner registered them correctly then there should be a suitable note on your Fahrzeugausweis.

That was for the rims only.
